GAS WATER-HEATER.

Specification of Letters Patent.

Patented April 10, 1906.

Application filed ry 18, 1905. Serial No. 246,215.

To all whom it may concern:

Be it known that I, DANIEL J OI-IN F. BUCK, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented a certain new and useful Improvement in GasWater Heaters, (Case No. 2,) of which the following is a full, clear,concise, and exact description, referencebeing had to the accompanyingdrawings, forming a part of this specification.

My invention relates to heating appliances, particularly to gasWater-heaters and its object is to provide improved and more eflicientarrangement and construction of the various heating and distributingmechanisms.

My invention may be best understood with reference to the accompanyingdrawings, in which Figure 1 is an elevation view of a vertical tubularboiler and heater, part of the shell being broken away to revealinterior arrangements. Fig. 2 is a top view of Fig. 1. Fig. 3 is asectional view taken on line 3 3 of Fig.

1. Fig. 4 is an enlarged sectional view taken on line 4 4 of Fig. 1..Fig. 5 is a sectional view taken on line 5 5 of Fig. 4. Fig. 6 is a planview of a bushing employed in assembling, and Fig. 7 is a sectional viewtaken on improved primary heater 4, which will be described more indetail later. The water-inlet pipe 5 supplies water to'the primaryheater and conveys the water thereto directly from a main or from theinterior of the storage tank 1, in which case the cold water isdelivered to the tank through the pipe 6, entering, as shown, throughthe top thereof. The water from the piping 5 circulates upwardly throughthe primary heater and absorbs the heat from the burner, the heatedwater passing through the outlet-pipe 7 and through the pipe 8 to thedistributing-piping 9 and to the source of consumption. YVhen no wateris consumed from .the distributing-piping 9, the heated water passesthrough the openings 10 10 at the upper end of the pipe-section 8 and isdelivered at the upper part of the storage-tank, from where it is laterdrawn upon opening of outlets connected with the di.s-.

tributing-piping. It will be noticed that the pipe-section 8 is ofgreater diameter than the piping 7 leading thereto from the primaryheater. The pipe 8 therefore acts as a reservoir or storage-compartment,particularly when the heated water is used immediately upon lighting ofthe burner. The pipe 7 being reduced impedes the flow of water thereto,and thus the water supplied to the primary heater is caused to lingermore or less therein to be more thoroughly heated before arriving in thesection 8. Furthermore, the pipe 8 acting as a reservoir prevents thesudden withdrawal of all the hot water through the distributing-pipe 9,which is also of less diameter than this storage-pipe. In heaters ofthis class heretofore the outlet-pipe from the primary heater was of'thesame diameter throughout, and the water-flow was not sufficientlyimpeded to allow rapid enough heating thereof to supply the primarydemand. The primary heater 4, with this arrangement of outlet-piping,forms a very efficient quick heating appliance independent of thestorage-tank and other apparatus.

The inlet-pipe 5 is preferably extended a distance upwardly in the tank.place, this prevents sediment or dirt from entering the pipe 5 andassists in the quick heating of the water, as the water entering thepipe is taken from near the top and much warmer than if taken from thebottom of the tank. The inlet-pipe 6 also is extended below the top ofthe pipe 5 to prevent the cold water therefrom from immediately enteringthe pipe 5.

The residual heat and gases from the burner pass through flues 1 1,which extend from the combustion-chamber upwardly through the interiorof the tank and opening through the top thereof. To prevent the coldwater at the bottom of the tank from absorbing the heat of the hot waterin the pipe 8, these fines are arranged to form a protective jacket orwall about the pipe 8, and to further shut out the cold water I providea pipe or shell 12, which surrounds the lower part of the fines and thepipe 8. The heat passing through the flues is thus confined and directedtoward the lower art of the pipe 8, and the nick heating of the water isthereby great y facilitated. Any heat left in the fiues after passagethrough the shell 12 is conveyed to the water at the upper part of thetank, and thus by this arrangement of piping, fines, and protectiveshell the available heat is "all In the first i ployed.

confined and directed in such a manner as to produce the most rapidefficient heating of the water.

As best shown in Figs. 4 and 5, the primary heater consists of an outerframe and an inner frame. The outer frame consists of upper and lowerannular flat heater-sections l3 and 14, connected by pipes orpassageways 15, which are threaded into the lower and upper walls,respectively, of the upper and lower sections. Any number of suchconnecting-pipes or passage-ways maybe em- Through the interior of eachpassage-way and through the annular sections fiues 16 16 are arranged,these flues being secured to the upper and lower walls, respectively, ofthe upper and lower annular sections, special bushings 17, such as shownin Figs. 6 and 7, being employed and provided with outer threads forengaging the wall of the upper section and with inner threads forengaging the threaded upper ends of the flues. The inner heater-frameconsists of the upper and lower annular heater-sections 18 and 19,arranged concentric with the corresponding sections of the outerheater-frame to leave annular passage-ways and 21. The lower and upperwalls, respectively, of these sections 18 and 19 are connected by thepipes 22, through which pass the fines 23 connected to the sections in asimilar manner as in the outer heater-frame sections. The inlet-pipe 5connects with the lower outer annular sec tion 14, and from adiametrically opposite point the connecting-pipe 24 connects with thelower inner annular section 19, thus causing the water to circulateentirely through the lower section before being admitted to the innerheater-frame. The water from the lower sections passes upwardly throughthe pipes 15 and 22 and circulates through the upper annular sectionsand between the sections through a connection 24 and from the center ofthe inner upper section passes upwardly through the piping 7 and 8 tothey distributing-pipin or to the upper part of the storage tank. Theheat from the burner 3 passes upwardly through the fines 16 and 23,through the annular passage-ways 21 and 20, and through the innerpassage-way 25* of the lower inner section, some of the heat alsopassing around the outer edge of the lower section. Thus the heat iscaused to circulate and to be directed against the entire exterior ofall the pipes and through the flues to the water passing through thepipes, and a very rapid heating is assured. To retard the flow of waterthrough the pipes 15 and 22, retarding means, such as spiraled wires 26,may be arranged about each flue. These wires cause agitation and spiralcirculation of the water through the pipe, the water being thus morereadily adapted to absorb a great amount of heat in a very short time.The residual heat from the primary heater passes upwardly through thefiues 11 and is confined, as before 1 described, to superheat the waterin pipe 8 and at the upper part of the boiler.

A hot-water heating arrangement of this construction is veryinexpensive, as it may substantially be built up of ordinary gas-piping,the only special parts being the annular heater-sections, thearrangement of the parts and the retarding and deflecting means employedcausing a more e'fficient and rapid heating of the water than anyheating devices heretofore employed.
